Ratio by Graph Tech Model # 4220-C0 (18:1 to 36:1) Bass Taper Shaft Configuration 2x2

Outstanding upgrade in every way

Outstanding tuning stability and build quality. The gear ratio feels perfect for precise adjustments on every string. Easily one of the best upgrades you can make.

Best tuners ever

These are really good tuners and fit my Warwick Streamer stage 2 perfectly. They look great and work great... smooth as silk!

Absolutely The Best!!!

I installed Ratio Bass tuners on both my 4 and 5 string Warwick Streamer II basses. My original tuners were 35 years old and worn out. I couldn’t be more pleased. These tuners are high end and well made. They fit and look great on my Warwicks. I usually check my tuning between every few songs when I’m gigging; especially when using fresh strings. I can fine-tune much faster now . These tuners turn easy and are very precise. I couldn’t be happier. I highly recommend GraphTech Ratio tuners!!!!
